Campagnolo super record crank hitting my frame

Hello All,

Desperately need some help, I have a set of Campagnolo Super Record Cranks on a 80's Colnago Super. When I span the cranks there was a strange noise, I then realised it was the rear protruding bits of the crank scratching the frame. Have I put these on wrong?

Any help much appreciated.

Thanks,

BB is too short. Get a longer one

Which BB is being used?

I am using a Campagnolo Record BB

I think you have to specify the axle length or, even better, the text stamped onto the axle surface (first get it out of the frame to read it)

Measure length A:

Okay, cartridge bearing (not automatically spit out by the vintage 80's Colnago?)
And the axle length is... mm ?

THis is getting silly, now can't get the crank off. Will get back to you when I have!

maybe that's what we get when ppl start riding fixed not because they've read of sheldon brown

It is 102mm.

Which is for the most recent Campag square tapered double cranks. The Campag pista BB is 111 mm. You need something similar I'd wager.

Thanks, this makes sense now. Anyone want to buy a campag record 102 italian thread bb?

Sorry about the amateur questions but is this what I need?

That kind of thing, but you need to find out your chainline then get the appropriate length BB.

I'm guessing you'll need something like a 111 mm but you can confirm this by doing the appropriate measuring.

If it is 111 then this is cheaper than the one you found but of equal quality;

I got a Veloce 111mm BB for 14 squids off Parker International website. Pretty sure thats what you'll be needing.

One last thing, my chainline was perfect with the bottom bracket I have now, the only problem was that I have double ring cranks and not Pista cranks so they had the bits poking out the back which just touched the frame. Does it make more sense to shell out for the Pista cranks or try a different bottom bracket?

I take it this thing is going to be fixed/single speed?

If you get new cranks you'll need a new BB too. Try the BB first. If it was marginal, you could try a slightly longer BB (eg not step up from 102 straight to 111, but try something in between. 108, for example, would move each crank arm out by 3mm ish.

or bodge, by filing off tabs or denting the frame where it touches.
